Before Elite: Dangerous 2.1, coordinates were calculated directly by EDSM with distances submission.
Now that we receive coordinates directly with the flight logs, distances submission has less impact on our database than before.

We still have a large number of systems in our database without coordinates, so it's always good to submit some ot to fill the gap in your old flight logs.

Why coordinates have different colors?

Before Elite: Dangerous 2.1, coordinates were calculated directly by EDSM with distances submission.
Now that we receive coordinates directly with the flight logs, we need to ensure that coordinates are not forged by malicious software.

To avoid that, we store all coordinates including the ones EDSM have calculated and show them with an orange color.
All these coordinates are pretty much precise as far as we know, but once we receive a log confirmation, we lock the coordinates and show them as green.

To be turned green, a system must receive multiple confirmation, so do not worry if they stay orange, this has no impact on your flight logs.
